As a BSc (Hons) Sports Therapist and MSc Strength & Conditioning Coach, I’ve lost count of the number of times an athlete or client has come to me complaining about knee pain, a stiff lower back, or recurring hamstring issues—only for the real problem to lie somewhere else entirely.

More often than not, the culprit is poor hip mobility.

The hips are one of the most powerful and influential joints in the human body. When they move well, everything above and below them tends to function better. When they don’t, the body compensates—and that’s when problems start to appear.

The Hips: The Body’s Central Engine

Your hips sit at the centre of your body, connecting your upper and lower halves. They are responsible for producing and transferring force during almost every athletic movement: running, squatting, jumping, rotating, changing direction, and even walking.

A healthy hip joint should move freely in multiple directions:

Flexion (bringing the knee toward the chest)
Extension (driving the leg behind you)
Internal and external rotation
Abduction and adduction (moving the leg away from or toward the body)

When mobility in any of these directions is limited, the body looks for the movement elsewhere.

And that’s where the trouble begins.

The Compensation Chain

The body is incredibly good at finding ways to complete a task—even if it means sacrificing efficiency or safety.

When the hips can’t move properly, two areas tend to pick up the slack:

1. The Lower Back

If the hips lack extension or rotation, the lumbar spine often compensates. Over time, this can lead to excessive loading, stiffness, and persistent lower back discomfort.

2. The Knees

Limited hip mobility—particularly in rotation and abduction—can cause the knee to collapse inward during movements like squatting, running, or landing from a jump. This places significant stress on the knee joint and surrounding structures.

In many cases, treating the knee or the back alone only provides temporary relief. Address the hip mobility, however, and the problem often resolves itself.

Modern Life Is Working Against Your Hips

One of the biggest challenges we face today isn’t sport—it’s sitting.

Long hours at desks, in cars, or on sofas encourage the hips to remain in a flexed position for most of the day. Over time, this can lead to:

Tight hip flexors
Reduced hip extension
Weak glutes
Limited rotational control

The result? A body that struggles when it’s suddenly asked to sprint, squat, or move explosively.

Performance Benefits of Better Hip Mobility

Improving hip mobility isn’t just about reducing injury risk. It can also unlock significant performance gains.

Athletes with good hip mobility often demonstrate:

Greater Power Production
Strong, mobile hips allow athletes to generate force more effectively when sprinting, jumping, or lifting.

Improved Movement Efficiency
When the hips move freely, energy transfers smoothly through the body rather than being lost through compensations.

Better Athletic Positions
From deep squats to powerful sprint mechanics, many key sporting positions rely on adequate hip mobility.

In simple terms: better hips often mean better performance.

Signs Your Hip Mobility May Be Limited

Some common indicators include:

Difficulty squatting below parallel
Persistent tightness in the hip flexors
Knees collapsing inward during squats or lunges
Lower back tightness after running or lifting
Reduced stride length when running

These signs don’t necessarily mean something is “injured,” but they do suggest that the hips may not be moving as freely as they should.

Mobility Is More Than Stretching

One of the biggest misconceptions I see is that mobility simply means stretching.

True mobility is a combination of three things:

Joint range of motion
Muscle flexibility
Strength and control within that range

It’s not enough to be flexible—you need to be able to control the movement as well.

This is why effective hip mobility training often includes a blend of:

Dynamic mobility drills
Strength work for the glutes and deep hip rotators
Controlled range-of-motion exercises
Movement pattern training (squats, hinges, lunges)

The Good News: Hips Respond Well to Training

The hip joint is highly adaptable. With the right approach, most people can see noticeable improvements in mobility within a relatively short period of time.

Even just a few minutes of targeted work in a warm-up or daily routine can start to restore movement quality.

For athletes, runners, and gym-goers alike, investing time in hip mobility is rarely wasted effort.

The Takeaway

If your body feels restricted, tight, or prone to recurring aches and pains, the answer may not be where the discomfort appears.

More often than people realise, the key lies in the hips.

Improve hip mobility, and you don’t just free up one joint—you unlock better movement throughout the entire body.

And when the hips move well, everything else tends to follow.
